Step wobble

Looking for an innovative fix to address step wobble. I can rock the step @1/4-3/8” at the step with my hand (I am 200 lbs). I have the TWC plug, which I drilled in place to 1/4” to get the 1/4 hole thru the bottom of the tubes. I replaced AN3 with AN4, after the step started to rock. I think I may have egged the 1/4” hole in the top of the tubes, by drilling the assy in the plane.

I’m thinking of machining a steel ring with a 1/4” wall x 1/2” wide to slip over the fixed white tube with a 5/16 Dia hole on both sides. Take the step and TCW plug out and drill the 5/16” hole separately instead of trying to drill the assy in the plane. Then replace AN4 with a longer AN5.

Thoughts/ideas.

Easier said than done, but great idea. The white tube can’t be removed (it can, but not worth that kind of effort on a painted plane) so some type of bushing/fixture and really tight 90° drill.

Thanks,
 
Leave current bolt installed and drill new hole 45-90deg off at a slightly deeper depth so both bolts can be installed at the same time.
